used rope eye splice double braid Class I
Class I ropes are made from any or all of the following fibers: olefin, polyester, or nylon.
This is an eye splice which can be performed on used rope. This is an all-purpose
splice techniqe designed for people who generally splice used rope as frequently
as new rope. It retains up to 90% of the average new rope strength and in used
rope up to the same proportion of residual used rope strength.
You may wish to read the supplemental information, "Special Tips for
Splicing Used Rope" (page 8), before beginning.
Splicing used rope can be made easier by first understanding the rope condition.
Natural shrinkage has occurred caused by water and heat. In addition, the cover
yarns have often been abraded. Soak the section of rope to be spliced in water
for several minutes ­ this lubricates and loosens fibers. 1 layer of tape

step
extracting the core
Bend rope sharply at X. With the pusher or any sharp tool such as
an ice pick, awl, or marlin spike, spread the cover strands to expose
core. First pry; then pull the core completely out of cover from X
to the taped end of the rope. Put one layer only on end of core.
Tip: After marking cover untape end of rope, grasp end of core, Prying out the core
and slide back cover pulling out core. This loosens and bunches
up cover strands in the area of Point X and makes it easier to open R
up cover strands for extraction. Also, thoroughly loosen 3-4 strand
pairs at X to assure a large and flexible hole for extraction, see left.

10 finishing the splice
step
Now untie the slipknot. If eye is not the right size, carefully check Steps 1 through 9.
If a hollow spot appears at the throat this means that the core tail was cut off too short.
Do not worry as this does not affect the splice performance nor its strength. Reason:
the total load of an eye splice is split between its own two legs. Therefore, each side
of the splice only has to support 50% of the total load. The braided cover alone can
handle this load factor.
You should whip the eye splice starting at base of throat
of eye, especially if rope is 1" diameter and larger.
